If the axle isn't bent from being overloaded (wear on outside of tire tread), then you're probably okay. If it's bent, you'd want to replace it. Since you don't know the axle capacity, we can make a pretty good guess if we know the bolt pattern of the wheel/hub as well as the inner and outer wheel bearing reference numbers. Knowing the axle capacity is important, so you can choose the proper replacement parts.

We offer a few standard sized 2K and 3.5K axles. To recommend a replacement, I'd need to know the hub face to hub face dimension as well as the spring center to spring center distance. I'll provide a diagram showing these measurements.

Since leaf springs can flatten out over time, the best way to get an accurate measurement of their length is to jack up the trailer so the axle hangs free and then measure the length. 25-1/4 is a common length spring for a 3500 lb axle.

For spring hangers, we don't offer a 4 inch tall hanger, but the # E4139 at 4-1/4 inches would be an acceptable replacement. For the rear hanger, use part # 115917. You'll also need 4 shackle straps, part # 115208GALV and 6 shackle bolts part # TRFA73Z916DLNZ.

If you're replacing axles, you'll also need U-bolts and plates. Which ones you'll need will depend on the diameter of your axle. If you can reply with the information I've requested above, I'd be happy to make further recommendations.

Answer 1

The 1-Leaf Double-Eye Spring #e46SR does not have a center bolt as found on the comparably-rated 6K spring #e34SR. That center bolt head, or pilot, is not present on the single leaf spring because it is not needed as it is with multi-leaf springs.…

The most common leaf spring length for trailer is 25-1/4 inches. The best recommendation I can make is the part #e46SR which is 25-1/4 inches long and is for 6k rated axles. You may need to move the hangers on your trailer to get these to fit, but…

The closest spring we have to that is part #e46SR which is a 6,000 pound 1-leaf spring but it measures 25-1/4 inches long. If your 26 inch spring is old and flattened out then there's a good chance part #e46SR is what you need because your old…

The 1-Leaf Double-Eye Spring for 6,000-lb Trailer Axles #e46SR that you referenced is not considered a one-time use leaf spring and would last a long time. While there isn't an exact mileage or age figure these springs were designed for they were…
